Since your PC has failed to start, the only way to enter Safe Mode is by tapping one of the Function keys in the top row of your keyboard. The Function key that takes you to Safe Mode varies by the make and model of your PC so check with your device manufacturer’s guidelines on how to activate Safe Mode. After booting in Safe Mode, follow these steps to run the SFC scan.

  1. Run Command Prompt as administrator by typing ‘cmd’ in the Start Menu search bar.
  2. Type this code in the Command Prompt window and initiate the process by pressing ‘Enter’.

sfc /scannow

Ultimate Fix for ‘Startup Repair Couldn’t Repair Your PC’: Rebuild BCD and Repair MBR

The ‘Startup Repair Couldn’t Repair Your PC’ error could very well occur if there’s a problem with your system’s Boot Configuration Data (BCD) or Master Boot Record (MBR). Your system will fail to start if these items go corrupt (and usually, that happens during major updates) so your BCD might need a rebuild before the system begins booting normally.

BCD and MBR can be repaired using the Windows Recovery Environment. During a BCD rebuild, the system’s boot configuration data is built from scratch while repairing the MBR works in favor of fixing issues with the partition table.

Steps to Repair MBR and Rebuild BCD

  1. You will need a bootable device with the same operating system that you plan to repair.
  2. Insert the bootable media in your PC and access the BIOS settings. Here, you will change the boot device priority.
  3. Restart after setting your bootable device as the primary startup option.
  4. You may be prompted to press any key to boot from installation media.
  5. Click on the option that says ‘Repair your computer’. You can find this option in the lower-left corner of your screen.
  6. Select the Troubleshoot option then click on ‘Advanced options’ and you will run into Command Prompt.

Execute the following commands:



bootrec /rebuildbcd

This command is for rebuilding boot configuration data from scratch.

The execution of these commands will take a considerable amount of time to complete. Unless you have a lot of unsaved data on the drive where you have the operating system installed, reinstalling Windows is the wisest thing to do.
